International Organizations

An international organization can be defined, following the International Law Commission, as an ‘organization established by a treaty or other instrument governed by international law and possessing its own international legal personality’. International organizations generally have States as members, but often other entities can also apply for membership. They both make international law and are governed by it. Yet, the decision-making process of international organizations is often ‘less a question of law than one of political judgement’.
